Easywatch is a major data analysis tool, product and solution provider in china. Since its inception, a large data and analytical service ecosystem has been developed, centred on a big digital user asset and algorithm model. At present, the visible products family consists of viewing thousands of sails, viewing ark and label clouds, which, as of the fourth quarter of 2017, cover 2,250 million smart terminals and monitor over 2. 66 million mobile applications. In the age of mobile internet, our way of life has become intellectual, and now banks have become our wallet housekeepers, and in order to serve more people, banks have introduced a number of preferential policies, ranging from internet sites to mobile phones, to optimize services. The app on the mobile phone is also a source of contention for banks. The question of how to create and how to improve user experience is a problem for banks, and it is time to analyse and show big data on the arks and canoes in order to solve them. Large financial markets, including banking services, have been the focus of attention and research, with more than 200 banking service applications for product-to-spectrum analysis tools under the flag of visuality, the regular issuance of trade lists and business analyses on a monthly basis, and the provision of solutions such as digital user graphics and product precision operations to enterprises in the context of finely refined business tools, such as a canoe. In the era of the app-dominated internet, the new wave financial assessment office officially launched the "bank 2018 app assessment". Over the past year, however, the banking sector has taken a comprehensive approach to the development of internet finance, which has largely resulted in an operational system of internet access + internet accounts + internet products. In the context of the increasing trend towards the mobileization of internet channels, mobile banking such as mobile banking, direct-selling banks and credit card app have become a priority for banks. The number of mobile bank users has continued to grow steadily, with new versions of mobile bank clients coming online to enhance the application of financial technology, create products and services and enhance user experience. In february 2018, there were 2,2,315. 45 million active users in banking service applications, an increase of 1. 09 per cent。
